This is a large Fresnel Lens focused on a copper tube with a 12 V pump (powered by two 6 watt solar panels) with water circulating through the unit. Water, seven gallons, was raised from 63 F to 106 F in one hour. It is not super efficient as heat is lost at the open top of the glass tank. This is designed to illustrate one method of solar heating a swilling pool with a Large Fresnel Lens.

Solar power pool heating can be home-made at low cost for those with low budget that cant pay the 1000 dollars, her’s a solution for aprox 300 dollars cost.
You need :
copper tubes
T-joints
flame torch
tin wire
“U” shaped extruded frame
rivet gun & rivets or use silicone to fix frame
galvanised steel sheet (paint black)
grey foam sheet insulator roll
spray paint can
5mm glass
silicon sealer
all working a 1m x 2m solar panel will give at least 60 degrees at water tap pressure….this is because the tubes are in parallel and the speed at which the water runs thru the tubes is lower than entry and exit, transferring maximum amounts of heat from the black painted tubes.
good luck!
